1.1.1.13 CCT_CounterOverflowCallbackRegister Function
C
void CCT_CounterOverflowCallbackRegister( CCT_CALLBACK callback, uintptr_t context )
Summary
Allows application to register a callback with the PLIB
Description
This function sets the pointer to a client/application function to be called "back" when the timer counter overflows. It also passes a context value (usually a pointer to a context structure) that is passed into the function when it is called. The specified callback function will be called from the peripheral interrupt context. The callback should be registered before starting the free running timer.
Precondition
CCT_Initialize() function must have been called first.
Parameters
Param | Description |
---|---|
callback | A pointer to a function with a calling signature defined by the CCT_CALLBACK data type. Setting this to NULL disables the callback feature. |
context | A value (usually a pointer) which is passed (unused) into the function identified by the callback parameter |
Returns
None
Example
void cct_counterOverflowCallback(uintptr_t context) { /* Handle free running timer counter overflow condition */ } CCT_CounterOverflowCallbackRegister(cct_counterOverflowCallback, 0);
Remarks
None
